Which component is tested annually as part of the release-detection system?

• A. Interstitial sensors
• B. Spill bucket
• C. SIR system
• D. Groundwater well

Answer: (A)

Release-detection systems rely on components that actively monitor for leaks and must be verified to ensure they will alert if a leak occurs. Interstitial sensors monitor the space between the primary containment and its secondary containment. They’re designed to detect liquid in that space, which signals a leak from the tank or piping. Regulators require an annual functional test of these interstitial sensors to confirm the sensors, wiring, and alarm circuits are working and that the interstitial space remains properly monitored. This annual check ensures that any leak would be detected promptly. Spill buckets are for catching spills at the fill point, not part of the continuous leak-detection pathway that’s tested annually. SIR systems (inventory-based detection) and groundwater wells serve other aspects of leak detection or environmental monitoring and aren’t the components that undergo the mandated annual functional test in the same way interstitial sensors do.
